This guy obviously has no clue about the blockchain and how it operates.

Government issued cryptocurrency is a joke. To start, most nations already have a digital currency since cash is rarely used in any for anymore.

Secondly, the power of crypto is in the blockchain that it resides upon...the de-centralized blockchain. When developers put something on that particular blockchain, they are creating more value to that chain. Who is going to put anything up on the rublechain which will reside on computers controlled by the Russian government and which can be taken down at any time.
